Passing value between Javascript and ASP.NET C# not working

While making a website I bumped into a problem. Because I dynamicaly create a "Detail" Button I need to make use of a Hidden Value to see "On Load" wether the button has been clicked.

Wegpage + Jquery part:

<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server">
    <link href="css/assortiment.css" rel="stylesheet" />
    <script src="js/jquery.js"></script>
    <script type="text/javascript">
        function detailKlik()
        {
            var hid = $('#<%=hd.ClientID %>');
            hid.val("true");
        }
    </script>
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
    <asp:HiddenField ID="hd" runat="server" Value="abc"/>
...

Whenever I press the dynamicaly generated button I can see that the javascript runs correctly. I can see the original value in the element.

I can even see the "Value" value is changing.

But when I debug in my c# code the value of the HiddenField is just back to the original.

Thank you :)

Solution

  • I have found the problem. Because I tried to access the Object's value in the method protected void Page_Init(...) I always got the default value. When I access the value in for example Page Load I see the correct value.

    Thank you!
